It was not until the sun was west that Jiang Yu returned to his hut through the space tunnel.

Xiaoqi is standing under the cherry tree, admiring the delicious cherries.

Jiang Yu saw that Xiaoqi had no youth at all, but had become a middle-aged man.

His appearance is different from Wei Xiang. He does not have the ultimate elegance, but has a sense of vicissitudes, and is more like a character before the Great Depression.

Xiaoqi saw Jiang Yu and he smiled slightly: "I originally wanted to call you grandpa, but when I saw your face, I couldn't call you this grandpa."

The two of them now look much younger than Xiaoqi.

Jiang Yu smiled and said, "It's good to have this kind of heart."

He glanced at the grass under the cherry tree. The space there was obviously stagnant, and then two rattan chairs and a coffee table appeared.

Jiang Yu made a gesture of asking for a seat, and Xiaoqi sat on one of the rattan chairs: "You seem to be used to your current life."

He paused and said, "For example, the usage of Galaxy Computer, often by observing your expressions and collecting information such as your habits, you can understand when and what services you need."

Jiang Yu also sat down: "I thought it understood my inner thoughts."

"There are also such technologies now," Xiaoqi smiled and said, "For example, the consciousness printer can print out the inner thoughts.

"But later, this type of product was gradually resisted because it was dangerous to expose people's inner thoughts. Therefore, although it was advanced and could improve efficiency, no one cared about it.

"Later Congress issued relevant laws, which greatly restricted the popularity of consciousness products."

The robot put the tea on, Jiang Yu took a sip of the tea and nodded: "The tea on Earth tastes much better than the tea I drank in the Qing Fei before."

Then he said: "I believe that the point I made before is still not outdated: often people need not the best and most advanced products, but the most suitable ones!"

"But this will affect the speed of human development!" Xiao Qi opened her arms and said, "Didn't you also popularize genetic technology when you were in office?"

Jiang Yu took a sip of tea, got up and picked two cherries, and Galaxy Computer brought a small basket with meticulously.

He said while picking cherries: "The popularization of genetic technology is because human development requires this technology."

Jiang Yu smiled warmly and said, "Don't be impatient, haste will lead to failure!

"The people's thoughts must keep up with the pace of development. I also take the consciousness printer you mentioned as an example.

"People's concern is that such tools will expose their own thoughts to others.

"Everyone has a dark side in his heart. If the dark side is not shown, then this person is a bright person in our eyes.

"What if you accidentally show your dark side when working with consciousness equipment?"

As he spoke, Jiang Yu ate a cherry, which was very sweet and delicious: "The three-body star people have an open mind, but their characteristics are destined to be unable to become advanced civilizations.

"Only with privacy can you have selfish ideas. Although we don't want to admit it, selfishness has greatly promoted the development of mankind.

"At least after you have privacy, you will start planning your own interests and let everyone develop in a roughly the same but obviously different trajectory.

"The development trajectory of the Three-Body Stars is too monotonous. Without private ownership, once they lose the pressure of survival, they will seriously lose the motivation to move forward.

"I don't know how historians now view the history of the Three-Body Civilization, but I think that the Three-Body Stars' people are the beginning of their weakness after leaving the harsh living environment."

Jiang Yu handed the cherry to Xiaoqi, and Xiaoqi waved her hand and said that she would not eat it.

Jiang Yu continued: "So the people's thoughts are not yet at the level of popularizing tools of consciousness.

"When people's consciousness is mainly light and they are not afraid of exposing their ideas, these tools can naturally become popular without you pushing them."

Xiaoqi took a sip of tea and frowned and said, "When will you have to wait?"

Jiang Yu spread his hands: "I don't know either."

Xiaoqi sighed: "What worries me the most has happened. Your thoughts seem to be closer to the historical school's ideas."

He said: "The historical school is too conservative. Have you not noticed that all the technological breakthroughs are basically the idea that was formed in the first two or three centuries of the Galaxy Age.

"We need newer ideas and updated theories to push us toward higher levels, otherwise our development may be powerless.

"I think we should vigorously develop the transformation technology between matter and matter, and the transformation technology between matter and energy, so that we can escape from traditional troubles such as energy and living space in the future."

"Xiao Qi, your idea is a bit taken for granted." Jiang Yu said: "I can tell you responsibly that I have experienced the first centuries of the Galaxy Age, but in that era no one knows which technologies and theories represent the future.

"The results you have developed now are the results of continuous trial and error after more than ten centuries.

"If you look at the source based on the results, it is naturally easy to clarify the logic in this, but at that time we didn't know what the future would be like.

"A lot of technologies and theories that were considered to represent the future at that time, the more they studied, the more they felt that they were useless. Many of the useless things can have multiple uses."

Xiaoqi no longer had the excitement she had just now and began to think seriously about Jiang Yu's words.

Jiang Yu ate a few cherries and continued: "Humans are lucky. We see the result of curvature flight from the Three-Body Stars; we see the result of space jumping from Venus; we see the result of two-dimensional technology from the singer civilization; we see the result of jumping flight from the paradise civilization and the gyroscope civilization.

“This reduces a lot of trial and error processes and has clear goals, otherwise our progress will be slower.

"You can refer to this point, ah, this example may have been a long time for you, let me briefly talk about it.

"In fact, the prototype of a steam engine was found in ancient Greece, but because there was no rubber at that time and the air-locking properties were too poor, the steam engine never attracted people's attention.

"Even if it was Watt, I just wanted to use a steam engine to pump water.

"If the ancient Greeks had seen a steam train, would the steam engine be buried for more than a thousand years?

"The Three-Body Stars did not destroy us in one breath, they should regret it because they let us, the 'ancients' see the 'steam train'."

Jiang Yu looked at Xiaoqi: "Your anxiety now mainly comes from your lack of vision and your future appearance.

"No one of us is a prophet. If we do our current affairs seriously, the future will not be too bad.

"Just like you mentioned the transformation technology of matter and matter, the transformation technology of matter and energy.

"This is a hypothesis proposed in the Age. It doesn't matter if it has not been realized yet. We just need to use the current technology to do our best to study it. Sooner or later, this technology will be realized!"

Xiaoqi seemed to have understood the essence of Jiang Yu's words.

Jiang Yu smiled and said, "I haven't given anyone a small meal for a long time."
